<span lang="EN-US">Brushless DC (BLDC) motor is widely used for various applications such as transportation. BLDC has many advantages compared to brush more compact, high robustness and simplest construction. The maintenance of this also low due absent the inside motor. For electric bicycle application, conventional electromagnetic torque because not properly designed. It faces density in...

General power system supply only provides a fixed voltage and frequency, and its the inverter is mostly used to control AC motor speed with different frequencies. However, it normally requires a rectified DC into AC for the frequency variation. In this study, a digital signal processing technology is developed to generate a Sine Wave Pulse Width Modulation (SPWM) signal to replace the tradition...

The considered converter-fed permanent magnet motor could alternatively be operated in two basically different states − the vector control mode or alternatively the brushless dc, also known as electronically commutated mode. Several quality aspects concerning the system performance have been comparatively investigated in practical as well as theoretical manner. Focus is thereby given to the num...

In Japan, room air conditioners, mainly heat-pump type, have been widely introduced into households. And "one unit to one room" really features today rather than "one unit to one home" in the past. In the circumstances where room-by-room air conditioning or all-season air conditioning systems are increasing, reduction of electric power consumption strongly required. As a consequence, the effici...

This paper presents an original study on the generated torque ripples of phase commutation in the Four-Switch, Three-Phase Inverter (FSTPI) Brushless DC (BLDC) motor drive which is suitable for low cost applications. Analytic values of torque ripple and commutation duration are obtained for different operation conditions. Moreover, limitation on the speed range operation caused from splitti...

The paper studies how the phase inductance of brushless DC torque motors affects their performance within high precision electric direct drives. Modified control laws for with are described, which optimize by various criteria. modified based on continuous regulation mutual attitude current and voltage vectors in motor windings. Parameters compared described applied, advantages use covered.
